Postoperative length of stay is an important outcome after colorectal cancer surgery.
Dr Sharma and colleagues from the United Kingdom evaluated the putative effects of personality, mood, coping, and quality of life on length of stay.
|The median length of stay was 10 days|
The research team identified a consecutive series of 110 eligible patients undergoing elective resection for colorectal cancer to participate in the study.
The team administered a battery of psychometric questionnaires including the Hospital Anxiety and Depression Scale.
The team also included the Functional Assessment of Cancer Therapy, the Courtauld Emotional Control Scale, and the Positive and Negative Affectivity Scale.
In addition, the researchers administered the Eysenck Personality Questionnaire 5 to 12 days before surgery.
Nonparametric correlations were computed for psychometric scores, demographic variables, and the length of stay.
The team entered factors that were to be significantly correlated on this analysis into a multiple regression model to determine the independent predictors of length of stay.
The researchers evaluated 104 patients with colorectal cancer participate, of which 67% were male and the mean age was 68 years.
The median length of stay was 10 days.
Length of stay was negatively correlated with pre- and postoperative albumin levels, and a positive effect with the Positive and Negative Affectivity Scale.
Functional Assessment of Cancer Therapy questionnaire with the colorectal module functional well-being score was negatively correlated with length of stay.
The research team noted that Eysenck Personality Questionnaire extroversion score was negatively correlated with length of stay.
The team found that length of stay was strongly positively correlated with postoperative morbidity.
Length of stay was positively correlated with Courtauld Emotional Control Scale anger score, age and being male.
Postoperative morbidity, and extroversion were independent predictors of length of stay.
Dr Sharmas' team concluded, "Personality as measured by Eysenck Personality Questionnaire predicts postoperative length of stay in patients with colorectal cancer."
"Extroverts have a higher pain threshold, and this may be part of the explanation."
